The shoot grows small green leaves. A Young Sapling The shoot grows very slowly. It turns into a young tree called a sapling. The rain, sun and soil help it to grow. The Mighty Oak It takes many years for the sapling to become an adult tree. After 20 years, the oak tree grows its own acorns. The acorns then fall to the ground. The life cycle starts again!
